About me
Hello! I am a Ph.D. student in Computer Science at Georgetown University located in Washington, DC. I am working with Prof. Lisa Singh on Data Science, Social Media Mining and NLP.
Most of my projects are collaborations with CNN, Washington Post, UMich and MDI on leveraging AI/ML methods for data-centric social concerns such as sentiment analysis, stance detection, force-migration, spam, misinformation and fake news.
News
- Three paper accepted at Machine Learning, LREC 2022, and DATA 2022 (to appear).
- I will join
Twitter as an ML intern working on misinformation this summer. - Our paper has been accepted at
The Harvard Misinformation Review. - I served as a reviewer at EMNLP 2021 and ACL 2022.
I joined
Google Cloud AI as a PhD intern.- Our paper has been accepted as a long paper at NAACL 2021.
- Our project with
known as The Breakthrough is reported weekly on CNN Politics. - Our paper has been published in the Journal of Computational Social Science.
- Our work about COVID-19 misinformation was reported on
Washington Post. - Started building this web page.

Software Engineer
Gather requirements, design, development, testing and validation using Ruby on Rails. Successfully developed APIs to reduce back-office operation time by 75% including PDF bill generation, email confirmation, bank account notification for Slack, etc.
Research in Neuroscience and Machine Learning mainly using MATLAB and C++. The advisor is Prof. Masayuki Numao. Collaboratively conduct experiments with the Biochemical Lab (Nagai Lab) and develop APIs to collect streaming data from EEG brainwave headset in C++ and apply ML model to evaluate user’s emotions.
Research Assistant
I was a member of Machine Intelligence and Knowledge Discovery Lab (MIND Lab) conducting research to solve data science problems in real-world including wind power prediction from power plants (time series), emotion prediction from brain wave (neuroscience and ML/AI) and analysis of course materials (text mining).
